Physics

On average, both arms and hands together account for 13% of aperson's mass, while the head is 7.0% and the trunk and legsaccount for 80%. We can model a spinning skater with her armsoutstretched as a vertical cylinder (head, trunk, and legs) withtwo solid uniform rods (arms and hands) extended horizontally.

Suppose a 62.0 kg skater is 1.60 m tall, has arms that are each64.0 cm long (including the hands), and a trunk that can be modeledas being 32.0 cm in diameter. If the skater is initially spinningat 80.0 rpm with her arms outstretched, what will her angularvelocity ω2 be (in rpm) after she pulls in her arms and they are ather sides parallel to her trunk? Assume that friction between theskater and the ice is negligible.

My answer was 293.93. Please show your work so I may trackbackwhere I went wrong thank you
